What's New in RubyMine 2019.2

Faster debugger

Our debugger used TracePoint :line to trace the program execution line by line. For v2019.2, we have designed a native extension for MRI that lets the debugger choose at which fragments of code the execution should be suspended, and free the rest of the code from overhead. As a result, we've been able to dramatically speed up the debugger and implement the new features below.

Smart Step Into

Previously, if you stumbled across a line with lots of methods in a debug session, RubyMine was only capable to step into the first method in a line. The newly added Smart Step Into lifts this restraint and allows you to step into and investigate every particular method or a block call located on the same line.

Block breakpoints

Pattern Matching

RubyMine 2019.2 supports Pattern Matching, which was introduced in the first preview of Ruby 2.7 as an experimental feature. The IDE identifies the new syntax and helps you navigate, find usages, and rename the objects.

Numbered block parameters

The new version of RubyMine recognizes the syntax of numbered parameters and shows/finds their usages. This is one more experimental feature of Ruby 2.7 which allows you to assign values in blocks using a parameter number as a default parameter, instead of defining a block variable.

Action Mailbox

RubyMine 2019.2 supports Action Mailbox which will ship with Rails 6. The IDE suggests autocompleting routing methods and callbacks, and navigates between their implementations and usages.

Enum support

We've added proper code insight support for ActiveRecord::Enum. This includes code autocompletion, navigation, and finding usages for enums’ names and methods. Negative scopes for enums, introduced in Rails 6, are supported as well.

Improved YARD support

Rename factories

New intention actions

The new Propagate to destructuring intention ( Alt-Enter ) allows you to replace an extra variable if possible with another destructuring. To remove a destructuring completely, use the intention action called Replace destructuring with property or index access.

Improved Rename refactoring

When you rename a symbol in a JavaScript or TypeScript file, the IDE now groups together dynamic usages and, by default, excludes them from the refactoring. This makes the refactoring more accurate and gives you more control over what exactly should be renamed in the Refactoring Preview tool window.

Better support for Vue.js component libraries

Code completion for components and their props from Vuetify, BootstrapVue, Quasar, and some other Vue component libraries is now more precise. This was made possible by a new approach we’ve adopted to working with these libraries in the IDE.

Searching for duplicate code

Improved EditorConfig support

With v2019.2 you can maintain different code styles in different parts of your projects by adding multiple .editorconfig files. In addition to the standard EditorConfig options, which have been supported for a long time, you can now use IDE-specific properties that cover all available IDE code style options.

Edit Shell scripts

The new version adds support for shell scripts. This includes code completion, quick documentation, textual rename for .sh and .bash files, and run configurations for shell scripts. The IDE also integrates with ShellCheck for linting and shfmt for formatting the code.

Autocompletion in .gitignore

In .gitignore files, the IDE now offers code completion suggestions for files and folders. Ctrl-click on the name to jump to this file or folder in the Project tool window. You can also quickly add files to .gitignore from the Project view and Local Changes tab – right-click on it and select Add to .gitignore.
